PRIORITY

The present application claims priority to Great Britain Patent Application No. 1318776.0, filed on Oct. 24, 2013, and all the benefits accruing therefrom under 35 U.S.C. §119, the contents of which are incorporated by reference in its entirety herein.

FIELD OF INVENTION

This invention relates to the field of assistive technology for people suffering from dementia or other cognitive affecting illnesses. In particular, the invention relates to providing assistive technology during interactive computer use.

BACKGROUND

Dementia is a non-specific illness syndrome in which affected areas of cognition may be memory, attention, language, and problem solving. Other illnesses or disabilities may also affect these areas of cognition.

People suffering from dementia, or similarly affecting conditions, have problems using software on a computer where numerous steps are required as they may get confused mid-way through a process. While using software, a user with impaired cognition, may forget the previous step or steps that they have taken. They may also get confused as to the operation they were in the process of carrying out or about to carry out.

As process steps in computer software use are often repetitive or similar in nature, steps may be easily confused by a user resulting in mistakes being made in a process. Such steps may be difficult to correct as going back in a process may lead to further confusion resulting in frustration and an inability to complete the task.

DETAILED DESCRIPTION

It will be appreciated that for simplicity and clarity of illustration, elements shown in the figures have not necessarily been drawn to scale. For example, the dimensions of some of the elements may be exaggerated relative to other elements for clarity. Further, where considered appropriate, reference numbers may be repeated among the figures to indicate corresponding or analogous features.

In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding. However, it will be understood by those skilled in the art that embodiments of the present invention may be practiced without these specific details. In other instances, well-known methods, procedures, and components have not been described in detail so as not to obscure the description.

Methods and systems are provided to keep track of actions performed by a computer software user, to determine a logical block to which specific patterns of actions relate, and, should the user stop mid-way through a process, remind the user of the steps already taken and/or the steps to follow.

Referring to FIG. 1, a flow diagram 100 illustrates an example embodiment of a described method.

At block 101, a tool is provided for monitoring a user's computer system and collecting and analyzing data relating to the user's interaction with the computer system. The monitoring may be carried out for all interactions with the computer system, or for specific computer programs or activities carried out by the user.

At block 102, the tool may build and store patterns of interaction and may update the patterns as new data is collected and analyzed, thereby providing a dynamically changing overview of the user's habitual interaction with the computer system.

At block 103, the monitoring of the user's interaction with the computer system may also be used to detect a hesitation or delay in the user activity indicating that the user may have lost track of the process he was carrying out. The hesitation may be detected by various methods described further below but generally recognizes an uncharacteristic delay in the user's interaction with the computer system.

At block 104, the steps carried out immediately prior to the detected hesitation are used, plus, optionally, other characteristics of the use, to match to stored patterns of the user interaction and to provide suggestions as to the next step(s) that should be performed by the user.

At block 105, one or more suggested steps may be presented to the user graphically and/or audibly depending on a user's preference.

The method includes the aspects of: tracking user interactions and storing data; using data to predict an intended outcome; and graphically presenting possible suggestions to the user dynamically.

Referring to FIG. 2, a flow diagram 200 illustrates an example embodiment of the aspects of blocks 101 and 102 of FIG. 1 of collecting and analyzing data relating to a user's interaction with a computer system.

At block 201, the tool may collect data relating to different aspects of the user's interaction with the computer system. The data may include inputs made to the computer system by the user via any input device such as a keyboard, mouse, touchpad, microphone, etc. The data may also include the processes carried out by the computer system in response to the user inputs.

The tool may constantly listen for user actions through the input devices and may look for computer actions performed in relation to the currently active window that might correspond to the user actions. The tool may also contain an in-built timer that may calculate the times between user actions. When an action or set of actions produces a computer action, the tool may map the action(s) to a specific result, storing the mapping as an atomic block of action→reaction.

The data may further include the rate at which the user interacts with the computer system, including different rates for carrying out different tasks, and the time of day and the day or date the interaction is carried out.

At block 202, the collected data may be analyzed including dividing the data into logical blocks of actions. For example, the user may use a browser to look through products online and then put them in the shopping basket and purchase them—this may be considered a single logical block. The detail level of the logical blocks may be set depending on the required level of assistance needed.

The logical blocks may be assigned categories, for example, based on the activity to which they relate (shopping, reading news, checking emails, etc.).

At block 203, the logical blocks may then be analyzed to determine the probability of a logical block following other logical blocks. This analysis may include the frequency at which different logical blocks are used or at which blocks of a given category are used. The frequency may be extended to the frequency of patterns or series of logical blocks. The probability of a logical block following other logical blocks may be used with logical blocks containing similar patterns, in order to calculate the probabilities of usage of certain blocks or patterns.

The analysis at block 203 may keep track of patterns used throughout a day and possible approximate time windows when certain patterns are used.

At block 204, the tool may calculate the average speed at which the user functions. This may be determined with respect to the logical blocks of activities. This enables the tool to determine if a hesitation at a step is irregular for a particular user. The predefined period that the tool may wait before prompting the user may be altered depending on the average speed of normal operation for that user.

In general, the tool will perform more efficiently if it stores and analyzes more data to build a detailed picture of a user's activities.

The tool may collect data, arrange it into patterns, assign categories (shopping, reading news, checking emails, etc.) to those patterns, calculate probabilities based on frequency of usage, and search for connections between different patterns. This data collection may build an initial set of patterns which may be continually updated and expanded as further user data is collected and analyzed. The tool may keep collecting data and updates existing patterns, hypotheses and user speed.

Patterns may include interconnections. For example, a user may always check his/her email after reading the news.

An example of pattern probabilities is as follows. A user might access a grocery store website twice a week. Once to look through products and add them to the basket for a future purchase (this may habitually be carried out on Fridays, for example) and once to purchase the accumulated products (for example, on Saturdays). Both sets of logical blocks may be assigned to a “shopping” category. Both might include logical blocks of adding products to the shopping cart. However, only one sequence or pattern will involve checking out the products and paying. Both of the sets of actions (browsing and purchasing) happen at an equal frequency of once a week each. However, the probability of one event happening is higher than the other based on the day of the week when the user is performing the action. On a Friday, it is more probable that the user is browsing. On a Saturday, it is more probable that the user is about to make a purchase.

For certain patterns, sub-patterns may also be created to aid the user if they hesitate and get lost within a pattern. For example, a shopping pattern might include:

-   -   i) Going to a shopping website;     -   ii) Logging in;     -   iii) Looking at the groceries;     -   iv) Putting groceries in a shopping basket; and     -   v) Checking them out.

Step i) might consist of the sub-pattern of:

-   -   a) typing in the name of the website; and     -   b) pressing enter.

Step ii) might consist of the sub-pattern of:

-   -   a) typing in the username;     -   b) typing in the password; and     -   c) pressing “Log in”; etc.

Referring to FIG. 3, a flow diagram 300 illustrates an example embodiment of the aspects of blocks 103 and 104 of FIG. 1 of monitoring the user's interaction to detect a hesitation and matching patterns to the user's activities.

At block 301, the tool may detect that a user stops interacting with the computer system midway through a pattern, for example, by failing to do anything within a pre-calculated average response time plus a given acceptable delay.

At block 302, the tool may have recorded that the user had just completed one or more logical blocks of activities and these logical blocks may be retrieved.

The completed one or more logical blocks of activities may be used at block 303 to match to stored patterns of logical blocks. In addition, other factors such as the time of the activity may be used for matching.

At block 304, it may be determined if there is more than one pattern that matches the user's activities. If there is only one pattern, then the next logical block in this pattern may be suggested at block 305 to the user as a prompt.

If there is more than one pattern that matches the user's activities, the probabilities of the patterns may be compared at block 306 and the most suitable pattern selected and suggested to the user at block 307.

Referring to FIG. 4, a schematic diagram 400 illustrates example logical blocks which may be used to analyze and match user activities in the described methods and systems.

A first logical block A 401 may be created with a category of email checking. The logical block A 401 may include the user actions of opening an email window, clicking on an unread message, and closing the email window.

A second logical block B 402 may be created with a category of online shopping. The logical block B 402 may include the user actions of typing the shopping website URL, and pressing enter.

A third logical block C 403 may be created also with a category of online shopping. The logical block C 403 may include the user actions of navigating to a username block, typing the username, and pressing the login button.

A fourth logical block D 404 may be created also with a category of online shopping. The logical block D 404 may include the user actions of browsing items and selecting an item.

The logical blocks A to D 401-404 may often be repeated by a user. The pattern may be repeated at approximately the same time of day or on a particular day of the week.

However, if the user hesitates in this sequence, for example, after logical block C 403 and does not start browsing items, the described tool may prompt the user that they have logged in to the shopping website and they may now start browsing for items.

Referring to FIG. 5, a schematic diagram 500 illustrates an example embodiment of the described method. The figure shows a current sequence of logical blocks 510 in the form of blocks A 511, B 512, C 513. Known patterns are searched and two known patterns 520 and 530 may be matched.

The first matched pattern 520 may include logical blocks A 521, B 522, C 523, followed by logical blocks D 524, E 525.

The second matched pattern 530 may include logical blocks A 531, B 532, C 533, followed by logical blocks F 534, G 535, H 536.

If the user stops interacting with the computer on logical block C, the patterns show that the next block of activity may be either block D 524 or block F 534. The tool may look at both patterns 520, 530 and if the probability of the first one is sufficiently higher than of the other, the user will be reminded of the steps in the first pattern. If the probabilities are equal, or are within a certain threshold, the tool may try to search for more information, looking at typical contexts, dates, times when each pattern was normally used and comparing it with current circumstances.

The tool attempts to find the most probable of patterns and may communicate the steps performed so far and the steps to follow to the user. This may be communicated, for example, via a message box or voice message.

A dynamically changing list of potential patterns with steps matching to the ones already taken may be shown or otherwise provided to the user with propositions of possible next steps.

Should the user perform a step that is not contained in any of the stored patterns, a new pattern may be created.

The described methods may be adapted for use by more than one user, with an option to specify which user is currently using the computer system in a given session. For example, this may be of use in a family situation in which more than one person requires assistive technology, or for a publicly used computer system.

Referring to FIG. 6, a block diagram shows an example embodiment of the described system 600 as a computer system 600.

A user system 601 may be any type of computing system used by a user. The computer system 600 may, for example, be a desktop or laptop computer, a tablet, a smart phone, etc.

This may be by monitoring user inputs, processes carried out by the computer or other events. The monitoring component 620 may include a timer 623. The monitoring component 620 may collect data relating to the user activity. A current activity component 621 may monitor a user's current interaction for data collection and for recording the current steps if a hesitation occurs. The monitoring component 620 may also include a delay detection component 622 for detecting a delay or hesitation in the user activity.

A data analysis component 630 may include a logical block component 631 for dividing user activity into logical blocks and a pattern component 633 for determining patterns of activity in the form of sequences of the logical blocks. A pattern update component 635 is provided for continually or periodically updating the stored patterns 636. A pattern probability component 634 may be provided for calculating, based on the frequency of logical blocks and patterns, the probability that a pattern is followed given initial known steps.

The data analysis component 630 may also include a reaction time component 632 for determining the average reaction time of the user in order to determine if a hesitation occurs. This average reaction time is used by the delay detection component 622.

The assistive tool 610 may include a pattern matching component 640 for matching a current sequence of steps which may be defined as logical blocks with stored patterns to determine the most likely next step that the user should take. A suggestion component 650 may provide the suggested next step to the user via an interface with the user system 601.
